For car and racing enthusiasts, AutoBlog put out a video of two M3 model BMWs driven by DTM drivers, going head-to-head around the circuit.

From AutoBlog:

"Roberto Ravaglia and Bruno Spengler, winners of the 1989 and 2012 championships, respectively, both showed up at the world-famous Hockenheimring with their title-winning cars. The two swapped seats, with Ravaglia taking the helm of Spengler's BMW M3 DTM racer and Spengler sliding behind the wheel of Ravaglia's first-generation M3 racer in the classic BMW Bank livery, and headed for the track. Spengler got a 23 second head start in the first-gen M3 with Ravaglia chasing behind."(Video after the jump)

Unlike the mainstream media's take that the chief competition for music streaming service, Spotify, is Apple's iTunes, music aficionados and mobile music listeners are far more frequently looking to distinguish between Spotify and Pandora. On the surface, Spotify allows you to use its service like both iTunes and Pandora; you can add songs to a queue, create playlists, and play a suggestive 'radio' for all playlists, to offer Pandora-like discovery.

SilverDoctors.com has created a compelling infographic, pairing conventional and modern currencies up head-to-head. The graphic relates the foundational, 3000 year old form of money, with the emerging digital form of money that's now 5 years old.

Ultimately, Silver Doctors concluded that "Bitcoins are certainly a very interesting development in the creation of money, especially given their decentralised nature and the fact that no ‘central bank’ is in control of their development...But in a few key areas gold still possesses crucial advantages."

Given the increased expectations placed on high-speed gaming and live streaming, the demand for greater performance from graphics cards is resulting in more options for consumers. The Verge.com takes a Head-to-Head look at two leading graphics cards for gaming dominance, comparing Nvidia and AMD.

The Verge article states that "AMD and Nvidia are now building hardware specifically designed for cloud gaming providers, which will eventually result in better performance for players looking to stream games on-demand from services like OnLive."
